GRAIN THRASHING AND SEPARATING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 250,248, dated November 29, 1881.

Application filed Juno 2, 1881. (ModeL) ments in grain thrashing and separating machines; and it has forits objects to provide an apparatus whereby the grain may be more thoroughly separated from the straw and rubbish than heretofore. This object we attain by the apparatus illustrated in the accompa- I nying drawings, in which-- Figure 1 represents a side elevation of our apparatus complete; Fig. 2, alongitudinal vertical section thereof; Fig. 3, a rear elevation; Fig. 4, a detached perspective view of aportion of the main shoeand grain-discharge chute 3 Fig. 5, a detached view of a portion of the stacker; Fig. 6, a transverse sectional view of the stacker; Fig. 7, a detached perspective view of the braces which in part support the main shoe of the apparatus; and Fig. 8 is a detached view of the concave-adjuster shaft.

The letter A indicates the frame of the apparatus, which is constructed of wood or other suitable material.

' At the forward end of the apparatus is located the usual thrashing-cylinder, the journals of which have their hearings in suitable boxes at the sides of the machine.

The letter B indicates a concaveadjuster, which is adapted to work in connection with the thrashing-cylinder, to control the admis sion of grain to the machine. The said adjuster consists of the two pivoted arms G, one

secured to each side of the apparatus, and a gitudinally "ibrating floor or bottom, which is supported on the link K, pivoted to the frame of the machine in such manner that it may move freely in a longitudinal direction.

The letter L indicates themain driving-shaft of the apparatus. This is provided with cranks M, which connect by the pitmen N with the vibrating floor or bottom I, by means of which areciprocating motion may be imparted to said bottom.

The letter P indicates an inclined riddle, which extends from the forward end to about the center of the apparatus, above the reciprocating bottom. The said riddle, at its forward ends, is supported by the pivoted links R, and at its rear ends is secured to the upper ends of the levers S, fulcru med to the frame of the apparatus. The lower ends of said 1evers have pivoted to them the forward ends of a rear riddle, T, the ends of which are supported by the pivoted links U in a manner similar to the forward riddle. The letter V indicates a comb located at the rear end of the forward riddle. The rear riddle is located directly over the main shoe and riddle A. This latter is supported from theframe of the apparatus by means of the braces 13 and springs O in such manner that it may oscillate freely laterally. The said shoe receives its motion through the medium of a vertical rockshaft, D, which connects, by a rod, E, with one of the pitmen N, the lower end connecting by means of an arm, F, with a rod, G, secured to the shoe.

The letter H indicates a rubbish-rack, constructed of slats, somewhat like a slatted window-shutter, and arranged directlyover a riddle, K, in shoe A. The said rack H is suspended by links I I, and connectedby means of springs K with the pitman N, by means of which the rack is shaken independently of the shoe A. The rack H, combined, as shown, with the main shoe, the riddle, and the vibrating bottom, swung independently ofeach other, is not designed to serve as a riddle nor as an extension of the straw-racks, but as a third rack to carry off the coarser rubbish and straw working through the two upper racks.

The letter L indicates a reciprocating bot tom, supported on links M, pivoted to the frame of the apparatus. The said bottom is connected with one of the pitmen N by means of a rod, P, whereby a reciprocating motion is given to said bottom.

The letter R indicates a grain-chute located at the forward end of the shoe A, immediately below the same. The said chute is supported upon swinging links S, pivoted to a cross-bar, T, which is suspended by links U, pivoted to the frame of the apparatus. By turning the links S a quarter of a revolution in either direction the grain-chute may be caused to deliver grain to either side of the apparatus.

The letter V indicates the stacker. This may be of the ordinary description. The sides are raised, as indicated by the letter W, by thickening the bottom at such parts to prevent the belt from wear.

At the tail of the apparatus is located a hinged comb, A below which is arranged a removable extension, B which can be detached when the apparatus is not in use, so as to prevent water, in the case of rain or storms, from finding its way and running down into the machine from the tail thereof.

The springs C have rectangular heads B which are secured to the inclined bearings B in such manner that the blades of the springs will be in line with the front pivot of the shoe.

The chute It receives a vibratory transverse motion through the medium of a rod, 0 con necting with a vertical rock-shaft, D which connects, in turn, by means of a rod, E with one of the pitmen N, from which it derivesits motion.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. The combination, in a grain-separator,of the concave of the thrashing-cylinder, the pivoted arms 0, a transverse shaft, D, the eccentries E on this shaft, the guides F on the frame, a ratchet-wheel, G, on said shaft, and a pawl, H, all substantially as described.

2. The combination, with the grain-chute R, of the jointed supporting-links S, the crossbar T, and the suspension-links U, whereby the chute can be inclined to the right or left and given an endwise shaking motion, substantially as described. 7

3. The combination of the bottom L, the comb A hinged to the main frame above the extension of bottom L, and the riddle T, having its tail end arranged above thejointed end of the comb, substantially as described.

at. The combination, with the shoe A,of the supporting-braces B, pivoted at their convergent ends, and the suspension-springs G,having their flat blades in planes radiating from the pivot of the said braces, substantially as described.

In testimony whereof we aflix our signatures, in presence of two witnesses, this 29th day of April, 1881.
